Thanks for the new screenshot. I saw, among other things:

...install-tl: open tlpdf(.../texlive.tlpdb) failed:
Permission denied at ...TLPDB.pm line 359.

Program Files, especially because, even on XP, this directory has
somewhat restrictive permissions.

https://www.tug.org/texlive/windows.html, in mind.   If it is true
that there should be no spaces in the path, then I think the
developers should definitely document that in the instructions.

If spaces in the path cause trouble, then we would consider that a
bug which we need to fix. But we can make no promises about
third-party scripts.

is no reason to do something, someone else thinks there is very good
reason to do the same thing.  And I am not going to argue here
whether there is indeed reason to put the unpack and install
locations under the same parent directory.  If merely doing so would
break the installer, then I have to say that there is room for

I am just trying to suggest things which may give you a better
chance of success.  We cannot possibly test every possible scenario.
Going with the defaults is the safe course.
